METALLIC VESSEL FOR SPECIFICATION forming part of Letters BROOKLYN, new YORK.

DOMESTIC PURPOSES.

Patent No. 3Ll,794, dated May 11, 1886.

Application filed March 25, 1886. Serial No. 196,472.- (No model.)

To all whom it may concern.-

Be it known that I, THOMAS BURKHARD, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Metallic Vessels and Receptacles for Domestic and other Uses, of which the following is a specification, reference being had to the accompanying drawings.

This invention is especially applicable for ash-receptacles, to take the place of ash-barrels for domestic use, but is applicable to alsubject to rough usage.

The object of the improvement is to give great stiffness to the sides of such vessels made of sheet metal, and to render them less liable to be defaced or destroyed by blows or by banging their exteriors against hard bodies.

The principal feature of the invention consists in the construction of the sides of such vessels of sheet metal, fluted at intervals in a substantially longitudinal direction, and with metal stiffening rods inserted within said flutes, and confined therein by the contraction tubular form.

The invention further consists in the novel combination,hereinafter set forth and claimed, involving such construction of the sides of metallic vessels.

Figure 1 in the drawings is aside elevation of a cylindrical vessel constructed according to my invention. Fig. 2 is a horizontal section of the same. Fig. 3 is a vertical section of the same in the plane indicated by the line 00 m in Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

The sides A A of the vessel may consist of a single sheet or plate of galvanized sheet-iron, tin-plate, copper, or other sufficiently ductile metal, and might be made of a single piece or sheet rolled up to the desired cylindrical or other form, and having its ends secured by seaming or riveting, and, if desired, by soldering; or they may consist of two or more pieces suitably united by seams or joints running lengthwise. In the example shown there are two pieces united by broad seams at a a. The metal is fluted at frequent intervals in the 1 direction which is to form the length of the vessel, and in each flute b is inserted a stiffening-rod, a, made of stout wire or other metal of round or any suitable transverse sectional form, and after the stiffening'rods c are inserted the flutes are contracted, as shown at b in Fig. 2, so as to nearly close them and confinethe stiffening-rods within them. When the metal is rolled up into the cylindrical or other form to make the sides of the vessel,the projections of the flutes are brought to the outside thereof, so that the inside of the plate or plates will present a substantially smooth, even, uninterrupted surface or contour for the reception of the bottom B and of a stiffeningrim, O, at the top. The bottom B represented consists of plate metal, having the margin turned down, as shown at din Fig. 3,and'inserted within the interior of the side A, to which it fits snugly and closely all round, owing to the flutes being thrown entirely outward, and so contracted as to make the interior of the sides present a practically uninterrupted surface. The lower part of the vessel is represented as further stiffened byastout iron hoop, e, which and the rim d are secured together and to A by rivets f through all three. The bottom might be further stiffened by such a cast-iron bottom frame as is included in my Letters Patent No. 317,620, dated May 12, 1885. The upper stiffening-rim, 0, consists of a band or hoop of metal, the lower portion of which, like the rim d of the bottom, fits snugly within A, and the upper portion of which, projecting above A, is turned over outward and wired, as shown atg in Fig. 3. This rim is shown as riveted to A by rivets h.

The bottom B and the upper strengtheningrim, 0, may be further united with the body or sides A by soldering.

It is obvious that vessels of this construction may have transverse section of other convenient forms besides the cylindrical.

WVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a vessel, of sheetmetal sides fluted at intervals in the direction of the length of thevessel, and stiffening-rods inserted within said flutes and confined therein by the flutes themselves, substantially as herein described.

2. The combination, in a vessel, of sides fluted outwardly in a longitudinal direction and presenting internally an even surface, stifiening-rods in the flutes of the sides, and a 5 bottom fitted and secured within the interior of the sides, substantially as herein described.

3. The combination, in a vessel, of the sheet-metal sides having longitudinal outwardly-projecting flutes, and stiffening-rods secured within and by the said flutes, and I0 havingan even interior surface, anda stiffeningband inserted within the said interior surface, substantially as herein described.
